Anonymous Network Transmission Method Based on Identity Mapping

Privacy issues are prevalent in network communications, where attackers can track and analyze sensitive information exchanged between communication parties, posing a threat to network communication security. On one hand, anonymous transmission mechanisms with multi-layer encryption can effectively protect user privacy. On the other hand, the concept of overlay networks can enhance security without modifying the existing network structure. In this paper, we designate the Identifier Network System as an internal network and design an anonymous network transmission method for inter-network communication. By designing nodes, the sending and receiving processes, data packet formats, tunnel transmission, distributed storage, and timely updates, we enhance the security of the transmission.
